Do you know of businesses running active fractional ownership/ asset tokenization investments (US, UK, Europe)?

I'm trying to explore real-world examples of asset tokenization platforms. Models where a physical or high-value asset is split into fractional ownership, where multiple investors can buy a percentage stake.

Would love to know:

• Credible platforms currently active

• Asset categories tokenized (art, domains etc.)

• Any firsthand experience (pros/cons)

Thanks!
